No Drawing. Application filed September 11, 1928, Serial No. 805,324, and in Czechoslovakia October 13, 1927.

The invention relates to blasting cart- 3. As a new explosive for use in blasting ridges, percussion caps, detonators, detonatcartridges, percussion caps, detonators, det ing. fuses, special projectiles and the like, onating fuses, special projectiles and the for the'production of which use is made of like 2,4,6-tri-nitro, 1,3,5-tri-azido benzene in- 2,4,6-trinitro 1,3,5-triazidobenzene either admixtures with a compressed layer of lead alone or together with other explosives such azide, weighing 0.05 to 0.2 grammes.

as trinitrotoluene, tetryl, tetra-nitro-penta- 4. As a new explosive for use in blasting erythritc and the like or admixtures such as cartridges, percussion caps, detonators, detpowdered glass, potassium chlorate, barium onating fuses, special projectiles and the nitrate, antimony tri-sulphide and the like like, a layer between one and two millimeters thick of 2,4,6-tri-nitro, 1,3,5-tri-azido as described in my copending application benzene in admixtures with a compressed Serial No. 305,323.

In blasting cartridges which were filled layer of lead azide, weighing 0.05 to' 0.2

with 2,4,6-trinitro 1,3,5-triazidobenzene grammes. ,ogether with other explosives or admixtures, In testimony whereof I have signed my it was found that the blasting cartridges name to this specification.

which was rammed with considerable pres- O.2 gs. or another azide of heavy metals or their compounds, were superior in action and shattering power to all the blasting cartridges hitherto known. For the purpose of protecting the layer of azide more satisfactorily, a protecting cap with a suitable aperture can be pressed on to the same simultaneously when ramming in the azide or another layer, one to two millimetres thick of 2,4,6-trinitro 1,3,5-triazidobenzene with a corresponding protective cap is applied with pressure to the azide layer.

The 2,4,6-trinitro 1,3,5-triazidobenzene necessary for carrying out the present in vention is made by causing a suitable solution. of 2,4,6-trichlor 1,3,5-trinitrobenzene, to react upon a suitable solution of an alkali azide.

VVhat'I claim is 1. As a new explosive for use in blasting cartridges, percussion caps, detonators, detonating fuses, special projectiles and the like 2,4,6-trinitro, 1,3,5-tri-azido benzene in admixtures with an azide of heavy materials.

2. As a new explosive for use in blasting cartridges, percussion caps, detonators, detonating fuses, special projectiles and the like 2,4,6-tri-nitro, 1,3,5-tri-azido benzene'in ad ixtures with a compressed layer of lead am e.
